R10 Four Flute End Mill 0.4μm Carbide Ball End Mill H6 For Steel

The AMG 4-flute solid carbide ball end mill is a precision CNC cutting tool engineered for 3D contouring, semi-finishing, and finishing operations in hardened steels, molds, dies, and aerospace alloys. Its ballnose tip and 4-flute design deliver exceptional surface finish, extended tool life, and optimal material removal rates in demanding machining applications.

• Solid Carbide Construction: Premium micro-grain carbide (0.4μm) provides maximum rigidity and wear resistance in materials up to HRC 60+, with reduced tool deflection for stable deep cavity machining.
• 4-Flute Design: Enables higher feed rates and improved surface finish compared to 2-flute designs, with balanced chip evacuation for efficient machining in steels and superalloys.
• Ballnose Tip (R0.5mm - R10mm+): Ideal for 3D profiling, mold/die finishing, and complex curvature machining with smooth transitions and minimal step-over marks.
• Advanced AlTiCrN Coating: Provides extreme heat and abrasion resistance for prolonged tool life, while reducing friction and built-up edge in challenging materials.
• Optimized for Hard Materials: Excellent performance in hardened tool steels (H13, P20, D2), titanium, Inconel, and specialized versions for graphite and composites.
• High-Speed Machining Ready: Stable cutting performance at high RPMs for reduced cycle times, suitable for HSM and trochoidal milling strategies.

• Precision mold and die finishing
• Aerospace component machining (blades, impellers)
• Medical device manufacturing (implants, prosthetics)
• Automotive and energy industry components (turbine parts, injection molds)

• Longer tool life than 2-flute designs in finishing operations
• Higher productivity through increased flute count
• Superior surface finish requiring minimal post-processing
